Remembering the 1996 Marcopper Mine Disaster
TheMarcopper Mining Corporation(Marcopper) started its mining operation in Marinduque Island in 1969.[1]Marcopper, a joint venture of Placer Dome[2],a Canadian mining company, (40%) and the Philippine Government,started its mining operations at the Mt. Tapian ore deposit, where copper concentrate,containing gold and silver was produced in the deposit.[3]
On March 24 1996, the Marcopper’sopen pit burst open and released 2 to 3 million cubic meters of mine tailinginto the Boac River in Marinduque killing marine life in the 26-kilometer waterway and floodedfarmlands and villages along its banks. Specifically, the incident’s impactsinclude the following: evacuation of 1200 residents;seriously affected approximately 700 families from 5 villages by loss of mostriver crossings;loss of road connections;inundation of between 6 and 10 hectares of cropland used for banana and otheragricultural purposes; deposition of tailings in the upper sections of theMakulapnit and Boac Rivers; loss of aquatic life, productivity and beneficial use of the rivers for domestic andagricultural purposes; and cleanup cost in US$80 million[4].
Anumber of cases has since been filed against Marcopper and Placer Dome and its officers, civil(3 cases with 1 international civil case), administrative and criminalcases (12 cases integrated inone). However, the people of Marinduquehas yet to attain justice. In 2005, the provincial government of Marinduque filed a landmark suit against Placer Dome and Barrick Gold Corp. for dumping millions of tons of minetailings into the Boac River in 1996.[5] The province at least $100 million from the company for the rehabilitation of the area,including the rivers of Marinduque.Placer Dome is also beingurged to pay for economic damages, including compensation for lost property andincome opportunities of the people, and for health problems caused by thetoxicity of the mine tailings.[6]
Thirteenyears after mine tailings spilled into the Boac River, leaving it biologically dead and endangeringthousands of human lives and public health, Marcopper Gold owes the Province ofMarinduqe Php 1.05 billion of unpaid property tax and Marinduqueñosare still saddled with millions of cubic meters of toxic open-pit copper mine waste[7]
